Help changing URLs on EvoTopsite script, (is this the correct forum?)

[Trevors]

Heya all,
Im currently runnin Evo Topsite script PRO version, i tryed to contact em but they have not replyed to my email i sent a week ago.
Anyways the URLs looks like this currently,  http://www.yourdomain.com/category/animals/ but i want to change it to
http://www.yourdomain.com/animals/ i mixed with the regular expression code once but messed it up, and not being able to enter the website.
regular expression code looks like this currently


RewriteEngine On
                 
RewriteRule ^sitedetails_([0-9]+).html <<path>>index.php?do=sitedetails&id=$1 [L]

RewriteRule ^comments_([0-9]+).html <<path>>index.php?do=comments&id=$1 [L]

RewriteRule ^category/([a-z_0-9]+)/ <<path>>index.php?cat_id=$1 [L]

RewriteRule ^user_([0-9]+).html <<path>>index.php?do=user&id=$1 [L]

problem is that admin login lays on yourdomain.com/admin
so im not sure how to fix it.
Would really appreciate some help.

Best Regards
Trevor
